A new school year has started at Canterlot High, among the new students there is Loving Blossom, a girl who may appear shy and weak, but who is actually the user of a rather strong Stand, which she calls Gutterflower. As the year passes by, things in Canterlot, both the town and the high school, don't seem normal, so Blossom has to unite with other Stand users to defeat an evil figure looming over this place.

This story is an indirect crossover with the manga and anime Jojo's Bizarre Adventure, mainly inspired by part 4, Diamond is Unbreakable (Because of the high school setting and murder mystery stuff)

[Rated T for some violence and occasional bloodshed]
